2 Claims. (Cl. 126-9) cept for the possible folding in of a handle or a stand.

attached thereto, the conventional stove is not collapsible, at least in the sense of reducing in size to a fiat package of approximately one half inch in thickness. The cost of the conventional barbecue stove as determined by the materials of construction and workmanship in its assembly is far too great to justify the consumer in disposing of the stove after an outing.

One of the objects of the present invention is to provide a disposable barbecue stove package unit.

Another object is to provide a disposable barbecue stove which can be assembled without tools, starting from flat members in sheet form.

Further objects and advantages of the invention will become apparent from the drawings and descriptions which follow.

In the accompanying drawings, Figure 1 shows a coneforming member fashioned from sheet material. Figure 2 shows a cone fashioned from the cone-forming member of Fig. 1. Figure 3 shows a cylinder-forming member of sheet material. Figure 4 shows a cylinder fashioned from the cylinder-forming member of Fig. 3. Figure 5 shows a base plate of sheet material. Figure 6 shows a section of an assembled cone, cylinder and base plate through 6--6 of Fig. 8. Figure 7 shows a grille member. Figure 8 shows a plan view of the complete assembly of the barbecue stove package unit. Figures 9, l0 and 11 show alternative embodiments of the cylinder-forming member of Fig. 3. Figure 12 shows an alternative embodiment of the cone-forming member of Fig. 1. Figure 13 shows an alternative embodiment of the stove assembly of Figure 6. Figure 14 shows another alternative embodiment of the stove assembly of Fig. 6. Figure shows a disposable barbecue stove package.

Referring to the accompanying drawings, a disposable barbecue stove package 1 (Fig. 15) is provided by assembling in a flat package such as a large envelope a coneforming member 2, a cylinder-forming member 3, a base member 4 and a grille member 5, together with suitable fastening materials such as cotter pins, bolts or wires.

The cone-forming member, the cylinder-forming member and the base plate may be made from any materials possessing sufiicient tensile strength and crush resistance to bear the relatively light load of barbecue fuel plus the chops, steaks or other foods which are cooked on the stove. At the same time, the materials of construction must have sufiicient flexibility to render possible assembly by hand without tools, and sutficient resistance to the heat produced in a barbecue stove to render the material feasible for the purpose. Sheet iron of 0.15 inch'thickness has been found quite suitable for all three parts of the stove. Sheet copper, brass or aluminum is also satisfactory. The gauge of the sheets can be varied over a fairly wide range. The component parts may be made from different materials. For example the cone-forming member may be made from sheet iron and the cylinderforming member from asbestos sheets of sufiicient thickness, for example, 0.125 inch. Brass, copper or aluminum, particularly when polished, make possible decorative effects for other uses for the assembled stove.

The cone-forming member 2 is desirably formed by stamping from sheet material a circular disc with a sector cut therefrom to form edges 6. Holes are punched in the cone-forming member 2 adjacent to the edges 6, for example at 7. The edges 6 are drawn one over the other to permit the punched holes at 7 on the respective ends to register for the purpose of inserting therethrough a suitable fastening means such as cotter pins, bolts or wire to form a cone 8. The tip of the cone 8 is cut away at 9 as shown in Fig. l to provide an aperture for a bolt 10 (Fig. 6) which may be used in the assembly of the parts of the stove. In a similar manner, holes may be punched-in the cylinder-forming member 3 near the ends 11, for example at 12, to permit the ends 11 to be drawn one over the other and the holes at 12 to register on the respective ends for the purpose of inserting there-.

through a suitable fastening means such as cotter pins, bolts or wire to form a cylinder 13.

The cone 8 thus formed is then inverted and placed into the cylinder 13 where it is permitted to rest on the upper edge 14 of the cylinder 13. A bolt 10 is placed into the aperture 9 of the cone 8 and passed through the aperture 15 in the base-forming sheet or base plate 4 and secured with a nut 16. Any other suitable fastening means may be employed in place of the bolt 10. The grille 5 is then placed on the top edge 17 of the cone 8 and the stove is then ready for use. The barbecue fuel 18 (Fig. 13), such as pellets or briquettes of charcoal or prepared fuel such as that described in my patent, U. S. 2,341,377 is placed in the cone 8 after removal of the grille 5.

Various alternative embodiments of the component parts of the disposable barbecue st'ove of this invention may be practiced. For example, the cylinder-forming member 3 may be provided with ears or tabs 19 (Fig. 9) as fastening means to be inserted in slits in the cone 8 and in the plate 4 and bent over by the fingers to secure the parts together in their intended relationship as in Fig. 14. Alternatively (Fig. 10), a combination of slots 20 and lugs 21 may be employed wherein the lugs 21 are passed through the slots 20 and bent over by the fingers. In another embodiment (Fig. 11), a circular aperture 22 and a corresponding circular lug 23 in the other end may be employed, the lug 23 being passed through the aperture 22 and bent over by the fingers. The coneforming member 2 may be fashioned with peripheral serrations 24 (Fig. 12) to provide additional openings between the cone 8 and the grille 5 for enhanced circulation. The base plate 4 may be backed with a sheet of asbestos paper 25 (Fig. 13) adhesively fastened thereto, as an insulation means in the event that the stove is used on a wooden floor. As an alternative, the base plate 4 may be provided with creased or partially slitted corners 26 (Fig. 5) which may be bent downward to provide legs for the base plate to raise it from a wood floor or to provide a means for levelling the stove on an irregular surface by adjusting the angle of the corners 26 with the base plate 4. The grille 5 may be formed from expanded sheet metal as shown in Fig. 7, or from wire mesh or any other suitable material.

In place of metal sheets for the cone-forming member Patented July s, 1958 3 Z, the cylinder-forming member 3 and or any of them, other sheet materials having satisfactory the baseplate 4,

cone, the cone being located on the cylinder with the apex of the cone within the cylinder and the surface of the cone in contact with the other circular edge of the cylinder; a connecting member secured to the base and the apex of the cone for securing the base, cylinder, and

cone in assembled relationship, and a grille member sup- As a result, the overall size of the disposable barbecue stove of this invention is much smaller in proportion to the amount of cooking that can be accomplished on it without refueling.

Those skilled in the art will readily understand that the manufacture of the disposable barbecue stove of this invention may be modified and varied to provide a desired set of characteristics in the ultimate device, assembled or unassembled, or in the interest of economy, without departing from the spirit of this invention, and it is therefore to be distinctly understood that the invention is not limited to the details of the foregoing disclosure, except as indicated in the appended claims. I claim:

1. A disposable barbecue stove comprising in combination: a base of heat-resistant sheet material; a rigid cylinder of heat-resistant flexible sheet material having detachable edges, and constituting a support, the cylinder being mounted on the base with one of the circular edges of the cylinder in contact with the base; a cone comprising a fire-pot of heat-resistant flexible sheet material havported by the circular edge of the cone.

2. A disposable barbecue stove comprising in combination: a base of sheet material; a rigid cylinder of flexible sheet material having detachable edges, the cylinder being mounted on the base with one of the circular edges of the cylinder in contact with the base; a cone comprising a fire-pot offlexible sheet material having detachably secured edges defining an element of the cone, the cone being located on the cylinder with the apex of the cone within the cylinder and the surface of the cone in contact with the other circular edge of the cylinder; and a connecting member secured to the base and the apex of the cone for securing the base, cylinder, and cone in assembled relationship.
